I have checked to make sure only one plug in was installed. There were two. I deleted the one I had earlier placed in the "Plug-in > File Formats" file. Because I read an old thread explaining that only one plug in can be installed at a time.

I can not find the original plug-in in the "plug-ins" folder. So I cannot delete it.

I tried using the adobe installer thinking it would uninstall the old plug in for me and it would not work.

I really have no idea what I am doing, I just followed instructions I found in this forum from years ago and was unsuccessful.

There are two File Formats plug-in folders (four on 64 bit systems). One in Program Files/Adobe/..., and one in Program Files/Common Files/Adobe/...Camera Raw goes in the latter, and on 64 bit installations there are two plug-ins, one for "Program Files" (64 bit) and one for "Program Files (x86)" (32-bit).

Keeping in mind that Adobe stops adding new camera support to older versions of Photoshop when they release a newer version (so in your case, Camera Raw 4.6 is the latest version that will work with Photoshop CS3), then you'll need to go look up whether your camera is supported in version 4.6.

In general, here's another way to check:

1. Look on one of the following two pages for the latest Camera Raw version update that works with your Photoshop version:

Hey, you put up a link I didn't know about (and which, with an edit, I thanked you for).

I actually answered his question in the other thread first, without seeing your answer, then copied the content of my answer there here, just to make sure he'd see it. Also, I saw that you didn't directly mention Adobe's policy of ceasing to add new camera support upon release of a newer version of Photoshop.

More info is better. Much more is much better! But I apologize if I stepped on any toes. I'll try to reign in my enthusiasm in the future.

I followed those steps. I cannot find any folder in my photoshop plug-ins > file formats folder that is named camera raw. So I can not remove my current camera raw file.

If I drop in the correct version of camera raw (4.6) for my version of photoshop (cs3 on a mac) it will appear as if I have two files in my 'file formats' folder when I run photoshop and look at the 'about plug-ins' drop down menue. (it lists two camera raw files).

When I clicked on help and checked for updates it tells me there are no updates available.

I feel like the real problem I am having is my inability to remove the original camera raw file from the plug-ins folder...

It is not my camera a photographer took photos of a few of my paintings and I would like to view/edit the raw files since he only gave me the NEFs and Jpegs and did not provide me with a tiff for any of the images.

I have edited raw images from other cameras I just can't get these images to open.

I am a PC person, so the terminology I'm going to use probably is not going to be correct. From what I've read, there are two libraries (or something like that), one is a main folder and the other is that a user folder. The plug in does not go in the user folder. The fact that you have two instances of Camera Raw listed in Photoshop indicates that the installation is wrong. You have to get rid of one of those, and then make sure the other one is installed in the right folder.

To ferret out multiple instances of the ACR plug-in, don't rely on the utterly useless and intrusive Spotblight or the Spotblight-driven Finder search function to find any files. Use the free Easy Find, which finds everything, including files Apple has declared off limits to Spotblight and the Spotblight-driven Finder search function.

1. What version of Camera Raw do you have? Choose Help - About Plug-in from within Photoshop. I ask, because you first need to understand whether you have the latest version of Camera Raw that works with your version of Photoshop.

2. If it's lower than 4.6, which is the latest revision that will work with Photoshop CS3, if you use the Adobe Updater (e.g., from the Help - Updates menu in Photoshop), do you not get the latest revision from Adobe, no muss no fuss?

Going to the folders and fooling with the files should be a last resort.
